A Client site of mine runs Samba 2.2.8a connecting to a series of Windows XP boxes via a Netgear Switch/Hub.
Earlier in the week they reported that certain applications, most notorously Symantec ACT were performing at super slow speeds.
A non site investigation showed that any file opened from the Server , copied to the desktop client was being copied at super slow speeds, as if all the bandwidth on the network had gone.
Checking configuration of the smb.conf and local machines proved no use at all and for a part of the hour I scratched my head as I tried to understand what was slowing down all file open, copy and move performance over the network.
Since local file activity ( on the server or client ) was more than adequate I was non plussed, until I reasoned that the only other device between Client and Server was the Network Switch.
A Quick power cycle of the Netgear switch later , and the performance was back where it should have been !
Just a salutory tail to tell really since the problem was neither Server or Client based, but the architecture was clearly malfunctioning.
Does anyone know of a test I could have carried out in order to trouble shoot that particular issue ?
